Rimrock

Rimrock, located at 1231 North 29th Street, Billings, MT 59101, is Montana's largest and most comprehensive nonprofit addiction treatment center, serving as a cornerstone of behavioral health and recovery services in the state for over five decades. Situated in Billings-the largest city in Montana-the facility offers a welcoming, professional environment focused on treating substance use disorders (alcohol, opioids/heroin/fentanyl/prescription painkillers, stimulants/methamphetamine/cocaine, benzodiazepines, marijuana, and polysubstance use) alongside co-occurring mental health conditions (dual diagnosis), including depression, anxiety, PTSD, trauma, bipolar disorder, and other behavioral health issues.

Rimrock provides a full continuum of care designed to meet individuals and families at every stage of the recovery journey. Services include:

• Medically supervised detoxification - safe, monitored withdrawal management (typically 3-10 days) with 24/7 nursing and medical oversight to address acute symptoms and stabilize clients.
• Residential/inpatient treatment - structured, immersive programs (usually 28-90 days) offering 24/7 support, individualized treatment plans, group and individual therapy, family education, and life skills development in a supportive residential setting.
• Adolescent residential treatment - specialized programs for teens (ages 13-17) with tailored care addressing developmental needs, family dynamics, and school reintegration.
• Partial hospitalization/day treatment (PHP) - intensive daytime programming for step-down or primary care without 24-hour residence.
• Intensive outpatient programs (IOP) - flexible group and individual therapy (3-5 days/week) for those transitioning or maintaining recovery while living at home.
• Outpatient counseling - ongoing individual, group, and family therapy for long-term support and relapse prevention.
• Family and community services - education, support groups, and counseling to help loved ones understand addiction and build healthy boundaries.

The clinical approach is evidence-based and trauma-informed, incorporating cognitive behavioral therapy (CBT), motivational interviewing, relapse prevention, 12-step facilitation, medication-assisted treatment (MAT) (buprenorphine, naltrexone, and other options when appropriate), family therapy, and holistic wellness practices (nutrition, mindfulness, physical activity). Rimrock is particularly recognized for its adolescent and family-focused programs, as well as its strong integration of community resources to support long-term success.

Rimrock is fully licensed by the Montana Department of Public Health and Human Services and holds CARF accreditation (Three-Year for multiple programs, including residential, outpatient, and detox services), reflecting adherence to rigorous national standards in quality, ethics, and outcomes. The center accepts Montana Medicaid, Medicare, most major private insurances (verification recommended), and self-pay/sliding scale options, with dedicated financial counselors assisting on coverage and affordability.

Since its founding in 1968 (originally as Rimrock Foundation), the organization has grown into Montana's leading provider of addiction and behavioral health services, helping tens of thousands of individuals and families achieve sobriety, stability, and renewed hope. Client testimonials and community reputation frequently praise the compassionate, professional staff, supportive and welcoming atmosphere, effective programming, and life-changing results-many describe Rimrock as the place where recovery truly begins and families are restored.
